19. 21 designates a spring connected to the arm 18 of the bell crank lever referred to, and anchored at any suitable point 22 of the horizontal and vertical frames 1 and 2. The other arm 23 of the bell crank lever has pivoted thereto at 2 1 the operating rod or lever 25 which is provided. withthe bottom yoke 26 which is secured tothe foot pedal 27 whichiS keyed at 28 to the bottom horizontal shaft 30 designates another foot treadle which is loose on the shaft 29 and which registers or aligns with the dog 32 which is keyed to the shaft 29 at 33. The shaft 29 is suitably journaled in brackets 35 carried by the bottom angle iron frame 3, as will be best understood from Figure 1. The operation is as follows: lVith the expansible frame 8 in its collapsed position shown in Figure 1, the operator draws the stocking to be inspected over saidframe with the knob 11 serving tospread or expand the toe portion of the stocking. W hen the stocking has been drawn over the frame 8, the operator depresses the left foot pedal 30 which is loose on the shaft 29 to bring pressure to bear'upon the dog 32 which is kcyed'to th shaft 29. This results in rotating the shaft 29 and thus pulling down on the operating lever 25 which in turn pulls down on the arm 23 of the bell crank lever, the other arm 18 of which is secured to the horizontal arm 19 thereby pulling the sliding block 15'towards the left hand side of Figure 1, thus bringing pressure to bear upon the sleeve or collar 6 which is carried by the inner frame or plate 5 to move the latter to the left hand portion with respect to the station ary frame 8, to change the angular relation of the links 9 with respect to the inner rigid frame 5 and the outer rigid expansible frame 8, and thus expand or spread out the outer expansible frame 8. The extent of expansion of the frame 8 is obviously determined by the extent of the pull on the operating arm 25, the pull on which is in turn determined by the rotation of the shaft 29. The rotation of the shaft 29 in this instance is limited by the contact of the left foot pedal 30 with the floor 36, and this preliminary expansion of the frame 8 serves to disclose the larger defects in the stocking being inspected, and if the operator notices a run or a dropped stitch, the operator refrains from further expanding the stocking to prevent further running of the dropped stitch, and the defective stocking is at once relegated to the repair department. Inthis way, the increase or exaggeration of defects is completely prevent ed, and minute inspection where it is not necessary is dispensed with; A second result of the depression of the left foot lever into contact with the floor 35 is that itbrings down the right foot pedal 27, which is in a relatively high position, to about the level of the left foot pedal shown in Figure 1, thus rendering the right foot pedal easily accessible to'the foot of the operator. This takes place because the right foot pedal 26 is keyed to the shaft 29, as above stated. If on a preliminary inspection of the stocking, after the preliminary expansion resulting from the operation of the left foot pedal 30, no defects are found, the operator then depresses the right foot pedal 27 down into Contact with the floor line 35, thus further rotating the shaft 29 which is keyed thereto and further pulling down on the operating arm 25, thereby further actuating the sliding block 15 to press against the sleeve 6 further to push the inner frame or plate 5 to the left hand side of Figure 1, through the instrumentality of the bell crank arm 18 and the actuating arm 16, further to expand the outer expansible frame 8 and further to stretch the stocking being inspected, to permit of minute examination to disclose such defects as were not obviously visible as a re sult of the preliminary or partial spreading of the stocking which resulted from the depression of the left foot pedal 30. Obviously when the pressure on the foot pedals 27 and r 30 is relieved, the spring 21 which is anchored to the arm 18 of the operating bell crank lever exerts a pull to the right hand direction of Figure 1, thereby moving the sliding block 15 through. the connecting arm 16, also in a right hand direction, thus withdrawing, the frame 5 in a right hand direction with re spect to the expansible frame 8, to collapse the latter into the position shown in Figure 1, whereupon the stocking can be removed. It is to be understood that the outer expansible frame 8 is loose on the sleeve 6, and that the sleeve 6 is loose on the shaft 7, and is connected to the sliding block 15 by any suitable swivel connection, so that the inner frame 5 and the outer frame 8 may be rotated orrevolved as a unit to permit the inspection of the stocking from all its sides.

It will thus be seenthat my novel stocking inspecting device embodies a two-step expansion of the stocking to be inspected, the expansion accomplished at each step being distinctly limited, and the two steps or operations being accomplished by the same mechanism, but successively and independently of each other. In describing my invention, I have shown an inner rigid frame 5 and an outer expansible frame 8, and have shown other details of construction of the frames 1 and 2, the spring 21, the connecting arm 16, the sleeve 6, the sliding block 15, only for the purpose of clearly illustrating my invention, but it is to be understood that all of these and other parts are to be considered as illustrative rather than limiting the scope of my invention which primarily resides in the provision of two foot pedals, one to expand the stocking to a predetermined extent to permit of a preliminary examination, and to bring the second pedal into operative relation pre-
